Bug Description

For 'Fill between many', in the Path Effects dialogue the paste icon is a page icon with a red X in it instead of being a clipboard icon. This is 0.92.0 r15299 under Windows; apparently it's also seen under Linux.

<opinion>
The icons used in the Path Effects dialog might need some review: the use cases of the 'edit-paste' icon in 'Envelope Deformation' and 'Fill between many', 'Fill between strokes' seem slightly contradicting:
* In Envelope Deformation, the button with the 'edit-paste' icon pastes the path data from the clipboard into the patheffect definition as bend path.
* In the Fill between many/strokes path effects, the button with the 'edit-paste' icon links the path on the clipboard to the patheffect definition via id reference.
* In Envelope Deformation on the other hand, the 'edit-clone' icon is used for the 'Link path' action (link via id reference).
